Pièce PEC/1 - Printed edition of 'A display of heraldry' by John Guillim

William Peckitt was born in Husthwaite, a village near Easingwold, the son of William, a fellmonger and glove maker, and his wife Ann. He was baptised on 13 April 1731. At some point prior to 1752 the family moved to York, where Peckitt worked in his father's glove making business before establishing himself as a glass painter in Colliergate, York.

Whilst the majority of his commissions were for painted glass, Peckitt also produced a small number of windows which included stained glass. In 1780 he patented an invention for 'blending coloured and stained glass'.

On 3 April 1763 Peckitt married Mary Mitley, daughter of the sculptor Charles Mitley. The couple had 4 daughters. Peckitt worked throughout his life on the maintenance of the medieval glass in York Minster as well as painting new windows there. He also undertook commissions for cathedrals, churches and houses throughout England. He produced windows for a number of colleges including the Alma Mater window for Trinity College.

Peckitt died on 14 October 1795 and was buried in the church of St Martin-cum-Gregory, York.
